                Appeal 2007-1170                                                                                 
                Application 10/971,698                                                                           
                length of the apertures, when there were more than one) was 440 mm in                            
                order to obtain a uniform deposition over a 300 mm long deposition region.                       
                (Freeman 013 at 9:[122].)  Freeman 013 discloses further that the baffles                        
                were 20 mm wide and spaced 2 mm from the cover.  (Freeman 013                                    
                at 9:[123].)  Thus, taking the lateral dimensions of the container to be                         
                slightly larger than the baffle (to permit the vapor to reach the apertures and                  
                to permit easy access and manipulation of the components), we may obtain                         
                an estimate of the minimum value of the ratio of the container volume to the                     
                baffle-to-cover volume.  Because Freeman 013 discloses in Example 3 that                         
                the container was filled to a level 2×b of 25 mm (Freeman 013 at 10[136]),                       
                the container must be at least 25 mm high, and we obtain a minimum                               
                container volume (converting to cm) of                                                           
                                   Lc × Wc × Hc = 44 × 2 × 2.5 = 220 cm3.                                        
                The baffle-to-cover volume is                                                                    
                                   Lb × Wb × Hbc = 44 × 2 × 0.2 = 17.6 cm3.                                      
                The minimum ratio of volumes is then:                                                            
                                     Lc × Wc × Hc   =  (220/17.6)  =  12.5.                                      
                                    Lb × Wb × Hbc                                                                
                It is evident by inspection that, given fixed lengths and widths of the                          
                container and baffle, and a fixed baffle-to-cover distance, the ratio of                         
                volumes is directly proportional to the height of the container.  Thus, we                       
                have no difficulty dismissing Freeman's objection that the references, in                        
                particular, Spahn, teach only relations among linear dimensions of the                           
                container and the baffle.  We must, of course, assume a level of ordinary
